| 1 | Efficacy and safety of over-the-scope clip: Including complications after endoscopic submucosal dissection显示文摘AIM: To retrospectively review the results of over-thescope clip (OTSC) use in our hospital and to examine the feasibility of using the OTSC to treat perforations after endoscopic submucosal dissection (ESD). METHODS: We enrolled 23 patients who presented with gastrointestinal (GI) bleeding, fistulae and perforations and were treated with OTSCs (Ovesco Endoscopy GmbH, Tuebingen, Germany) between November 2011 and September 2012. Maximum lesion size was defined as lesion diameter. The number of OTSCs to be used per patient was not decided until the lesion was completely closed. We used a twin grasper (Ovesco Endoscopy GmbH, Tuebingen, Germany) as a grasping device for all the patients. A 9 mm OTSC was chosen for use in the esophagus and colon, and a 10 mm device was used for the stomach, duodenum and rectum. The overall success rate and complications were evaluated, with a particular emphasis on patients who had undergone ESD due to adenocarcinoma. In technical successful cases we included not only complete closing by using OTSCs, but also partial closing where complete closure with OTSCs is almost difficult. In overall clinical successful cases we included only complete closing by using only OTSCs perfectly. All the OTSCs were placed by 2 experienced endoscopists. The sites closed after ESD included not only the perforation site but also all defective ulcers sites.RESULTS: A total of 23 patients [mean age 77 years (range 64-98 years)] underwent OTSC placement during the study period. The indications for OTSC placement were GI bleeding (n = 9), perforation (n = 10), fistula (n = 4) and the prevention of post-ESD duodenal artificial ulcer perforation (n = 1). One patient had a perforation caused by a glycerin enema, after which a fistula formed. Lesion closure using the OTSC alone was successful in 19 out of 23 patients, and overall success rate was 82.6%. A large lesion size (greater than 20 mm) and a delayed diagnosis (more than 1 wk) were the major contributing factors for the overall unsuccessful clinical cases. The location of the unsuccessful lesion was in the stomach. The median operation time in the successful cases was 18 min, and the average observation time was 67 d. During the observation period, none of the patients experienced any complications associated with OTSC placement. In addition, we successfully used the OTSC to close the perforation site after ESD in 6 patients. This was a single-center, retrospective study with a small sample size. CONCLUSION: The OTSC is effective for treating GI bleeding, fistulae as well as perforations, and the OTSC technique proofed effective treatment for perforation after ESD. | Noriko Nishiyama Hirohito Mori Hideki Kobara Kazi Rafiq Shintarou Fujihara Mitsuyoshi Kobayashi Makoto Oryu Tsutomu Masaki | 2013 | World Journal of Gastroenterology2013，19，18： | 42 |
| 2 | 不同溶剂提取芦竹化感物质对铜绿微囊藻生长的影响显示文摘研究并比较了3种极性不同的有机溶剂(甲醇、乙酸乙酯、正己烷)提取的芦竹(Arundo donaxLinn.)化感物质对铜绿微囊藻生长的影响.通过跟踪观察藻细胞形态,测定藻细胞密度和细胞大小,发现3种溶剂提取物对铜绿微囊藻均有抑制作用.抑藻作用出现早晚次序:甲醇提取物<乙酸乙酯提取物<正己烷提取物.随作用时间的延长,投加低浓度甲醇提取物藻细胞生长恢复明显,高浓度抑藻效果较乙酸乙酯提取物及正己烷提取物弱.高浓度乙酸乙酯提取物、正己烷提取物在分别作用2 d、4d后,抑藻效果均接近100%.各溶剂提取物的半效应质量浓度(EC50,6 d)分别为甲醇提取物0.17 g.L-1,乙酸乙酯提取物0.05g.L-1,正己烷提取物0.08 g.L-1.研究同时发现,投加甲醇提取物藻细胞空洞化,投加乙酸乙酯提取物藻细胞空洞化、破碎以及部分抱团,投加正己烷提取物藻细胞出现褶皱及聚团现象.各溶剂提取物均引起铜绿微囊藻细胞体积减小,其中乙酸乙酯提取物的效果最强. | 洪喻 胡洪营 黄晶晶 Sakoda kiyoshi Sagehashi Masaki 李锋民 | 2008 | 环境科学2008，29，11： | 33 |
| 3 | Comparison between combination therapy of percutaneous ethanol injection and radiofrequency ablation and radiofrequency ablation alone for patients with hepatocellular carcinoma显示文摘AIM: In the present study, the characteristics of PEI-RFA treatment were further elucidated by analyzing the relationship between the volume of coagulated necrosis and the energy requirement for ablation or the amount of ethanol injected into HCC.METHODS: The volume of coagulated necrosis, total energy requirement and energy requirement for coagulation of per unit volume were examined in the groups of PEI-RFA and RFA alone using the Cool-tip RF system.RESULTS: The results showed that the volume of coagulated necrosis induced was significantly larger in PEI-RFA group than in routine RFA group, when the total energy administered was comparable in both groups.In PEI-RFA, enlargement of coagulated necrosis was admitted in 3 dimensions and the amount of energy requirement per unit volume of coagulated necrosis was negatively correlated with the amount of ethanol injected into HCC.CONCLUSION: These results suggest that, compared to RFA alone, PEI-RFA enables to induce comparable coagulated necrosis with smaller energy requirement, and that PEI-RFA is likely to be less invasive than RFA alone irrespective of inducing enhanced coagulated necrosis.Thus, simple prior injection of ethanol may make RFA treatment more effective and less invasive for the treatment of patients with HCC. | Kazutaka Kurokohchi Seishiro Watanabe Tsutomu Masaki Naoki Hosomi Yoshiaki Miyauchi Takashi Himoto Yasuhiko Kimura Seiji Nakai Akihiro Deguchi Hirohito Yoneyama Shuhei Yoshida Shigeki Kuriyama | 2005 | World Journal of Gastroenterology2005，11，10： | 29 |
| 4 | Efficacy and safety of emergency endoscopic retrograde cholangiopancreatography for acute cholangitis in the elderly显示文摘AIM To investigate the efficacy and safety of emergency endoscopic retrograde cholangiopancreatography(ERCP) in elderly patients with acute cholangitis. METHODS From June 2008 to May 2016, emergency ERCPs were performed in 207 cases of acute cholangitis at our institution. Patients were classified as elderly if they were aged 80 years and older(n = 102); controls were under the age of 80 years(n = 105). The patients' medical records were retrospectively reviewed for comorbidities, laboratory data, etiology of cholangitis(presence of biliary stones, biliary stricture and malignancy), details of the ERCP(therapeutic approaches, technical success rates, procedure duration), ERCP-related complications and mortality. RESULTS The frequency of comorbidities was higher in the elderly group than the control group(91.2% vs 67.6%). Periampullary diverticulum was observed in the elderly group at a higher frequency than the control group(24.5% vs 13.3%). Between the groups, there was no significant difference in the technical success rates(95.1% vs 95.2%) or endoscopicprocedure durations. With regard to the frequency of ERCP-related complications, there was no significant difference between the two groups(6.9% vs 6.7%), except for a lower rate of post-ERCP pancreatitis in the elderly group than in the control group(1.0% vs 3.8%). Neither angiographic nor surgical intervention was required in any of the cases with ERCP-related complications. There was no mortality during the observational periods. CONCLUSION Emergency ERCP for acute cholangitis can be performed safely even in elderly patients aged 80 years and older. | Gen Tohda Masahiro Ohtani Masaki Dochin | 2016 | World Journal of Gastroenterology2016，22，37： | 28 |
| 5 | A case of invasive hemolymphangioma of the pancreas显示文摘Hemolymphangioma of the pancreas is a very rare benign tumor. There were only five reports of this disease until March 2008. Herein, we report a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to duodenal invasion. A 53-year-old man had been admitted a referral hospital because of severe anemia due to gastrointestinal bleeding in December 2005. He was then transferred to our institute with a diagnosis of a tumor of the head of the pancreas with duodenal invasion in January 2006. No abnormalities were revealed except for anemia in laboratory data including CEA and CA19-9. Gastrointestinal endoscopy revealed bleeding at the duodenum. Computed tomography also demonstrated a heterogenous mass at the pancreatic head and suspected invasion to the duodenal wall. Ultrasonography showed a huge mass at the pancreatic head with a mixture of high and low echoic areas. Pylorous-preserving pancreatoduodenectomy was performed. The pancreatic tumor was soft and had invaded to the duodenum. The pathological diagnosis was a hemolymphangioma of the pancreas invaded to the duodenum. His postoperative course was uneventful and he was discharged on the 26th d after surgery. Hemolymphangioma of the pancreas is a very rare benign tumor. In a literature review until March 2008, we found five case reports. Major symptoms are abdominal pain and distension due to the enlarged tumor. However, we experienced a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to invasion to the duodenum. This disease is a very rare entity, but should be considered when patients have gastrointestinal bleeding. | Yoshikazu Toyoki Kenichi Hakamada Shunji Narumi Masaki Nara Daisuke Kudoh Keinosuke Ishido Mutsuo Sasaki | 2008 | World Journal of Gastroenterology2008，14，18： | 26 |
| 6 | Gastric adenocarcinoma of fundic gland type:Endoscopicand clinicopathological features显示文摘Gastric adenocarcinoma of fundic gland type(GA-FG) with chief cell differentiation was recently proposed as an extremely rare type of gastric adenocarcinoma. Here, we report 4 cases of GA-FG with chief cell differentiation. Endoscopic features included a submucosal tumor shape or a flat shape, whitish discoloration and dilated vessels on the surface. The tumors were located in the upper or middle third of the stomach. All cases were preoperatively diagnosed as GA-FG by biopsy, and endoscopic submucosal dissection was performed. Resected specimens revealed well-differentiated adenocarcinomas resembling chief cells. Tumor cells were diffusely positive for pepsinogen-Ⅰ, but partially positive for H+/K+-ATPase in scattered locations around the tumor margin. Despite the presence of minimal invasion of the carcinoma into the submucosal layer, which was observed in two cases, neither lymphatic nor venous invasion was detected in any of the cases. Finally, all cases showed less aggressive clinical behavior with low grade malignancy. | Gen Tohda Takeshi Osawa Yasuyuki Asada Masaki Dochin Shintarou Terahata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，4： | 26 |
| 7 | Retrospective cohort study Lower incidence of complications in endoscopic nasobiliary drainage for hilar cholangiocarcinoma显示文摘AIM:To identify the most effective endoscopic biliary drainage technique for patients with hilar cholangiocarcinoma.METHODS:In total,118 patients with hilar cholangiocarcinoma underwent endoscopic management[endoscopic nasobiliary drainage(ENBD)or endoscopic biliary stenting]as a temporary drainage in our institution between 2009 and 2014.We retrospectively evaluated all complications from initial endoscopic drainage to surgery or palliative treatment.The risk factors for biliary reintervention,post-endoscopic retrograde cholangiopancreatography(post-ERCP)pancreatitis,and percutaneous transhepatic biliary drainage(PTBD)were also analyzed using patient-and procedure-related characteristics.The risk factors for bilateral drainage were examined in a subgroup analysis of patients who underwent initial unilateral drainage.RESULTS:In total,137 complications were observed in92(78%)patients.Biliary reintervention was required in 83(70%)patients.ENBD was significantly associated with a low risk of biliary reintervention[odds ratio(OR)=0.26,95%CI:0.08-0.76,P=0.012].Post-ERCP pancreatitis was observed in 19(16%)patients.An absence of endoscopic sphincterotomy was significantly associated with post-ERCP pancreatitis(OR=3.46,95%CI:1.19-10.87,P=0.023).PTBD was required in 16(14%)patients,and Bismuth type III or IV cholangiocarcinoma was a significant risk factor(OR=7.88,95%CI:1.33-155.0,P=0.010).Of 102 patients with initial unilateral drainage,49(48%)required bilateral drainage.Endoscopic sphincterotomy(OR=3.24,95%CI:1.27-8.78,P=0.004)and Bismuth II,III,or IV cholangiocarcinoma(OR=34.69,95%CI:4.88-736.7,P<0.001)were significant risk factors for bilateral drainage.CONCLUSION:The endoscopic management of hilar cholangiocarcinoma is challenging.ENBD should be selected as a temporary drainage method because of its low risk of complications. | Kazumichi Kawakubo Hiroshi Kawakami Masaki Kuwatani Shin Haba Taiki Kudo Yoko A Taya Shuhei Kawahata Yoshimasa Kubota Kimitoshi Kubo Kazunori Eto Nobuyuki Ehira Hiroaki Yamato Manabu Onodera Naoya Sakamoto | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，9： | 26 |
| 8 | Gastric adenocarcinoma of the fundic gland(chief cell-predominant type): A review of endoscopic and clinicopathological features显示文摘Gastric adenocarcinoma of the fundic gland(chief cellpredominant type, GA-FG-CCP) is a rare variant of welldifferentiated adenocarcinoma, and has been proposed to be a novel disease entity. GA-FG-CCP originates from the gastric mucosa of the fundic gland region without chronic gastritis or intestinal metaplasia. The majority of GA-FG-CCPs exhibit either a submucosal tumor-like superficial elevated shape or a flat shape on macroscopic examination. Narrow-band imaging with endoscopic magnification may reveal a regular or an irregular microvascular pattern, depending on the degree of tumor exposure to the mucosal surface. Pathological analysis of GA-FG-CCPs is characterized by a high frequency of submucosal invasion, rare occurrences of lymphatic and venous invasion, and low-grade malignancy. Detection of diffuse positivity for pepsinogen-I by immunohistochemistry is specific for GA-FG-CCP. Careful endoscopic examination and detailed pathological evaluation are essential for early and accurate diagnosis of GA-FG-CCP. Nearly all GA-FG-CCPs are treated by endoscopic resection due to their small tumor size and low risk of recurrence or metastasis. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2016 | World Journal of Gastroenterology2016，22，48： | 26 |

| 11 | ABO incompatible renal transplants:Good or bad?显示文摘ABO incompatible kidney transplantation(ABOi-KT) was previously considered to be an absolute contraindication for patients with end-stage kidney disease(ESKD) due to hyperacute rejection related to blood type barrier. Since the first successful series of ABOi-KT was reported, ABOi-KT is performed increasingly all over the world. ABOi-KT has led to an expanded donor pool and reduced the number of patients with ESKD awaiting deceased kidney transplantation(KT). Intensified immunosuppression and immunological understanding has helped to shape current desensitization protocols. Consequently, in recent years, ABOi-KT outcome is comparable to ABO compatible KT(ABOc-KT). However, many questions still remain unanswered. In ABOi-KT, there is an additional residual immunological risk that maylead to allograft damage, despite using current diverse but usually intensified immunosuppressive protocols at the expense of increasing risk of infection and possibly malignancy. Notably, in ABOi-KT, desensitization and antibody reduction therapies have increased the cost of KT. Reassuringly, there has been an evolution in ABOiKT leading to a simplification of protocols over the last decade. This review provides an overview of the history, outcome, protocol, advantages and disadvantages in ABOi-KT, and focuses on whether ABOi-KT should be recommended as a therapeutic option of KT in the future. | Masaki Muramatsu Hector Daniel Gonzalez Roberto Cacciola Atsushi Aikawa Magdi M Yaqoob Carmelo Puliatti | 2014 | World Journal of Transplantation2014，4，1： | 18 |
| 12 | Diagnosis of autoimmune pancreatitis显示文摘Autoimmune pancreatitis(AIP) is a distinct form of chronic pancreatitis that is increasingly being reported. The presentation and clinical image findings of AIP sometimes resemble those of several pancreatic malignancies, but the therapeutic strategy differs appreciably. Therefore, accurate diagnosis is necessary for cases of AIP. To date, AIP is classified into two distinct subtypes from the viewpoints of etiology, serum markers, histology, other organ involvements, and frequency of relapse: type 1 is related to Ig G4(lymphoplasmacytic sclerosing pancreatitis) and type 2 is related to a granulocytic epithelial lesion(idiopathic duct-centric chronic pancreatitis). Both types of AIP are characterized by focal or diffuse pancreatic enlargement accompanied with a narrowing of the main pancreatic duct, and both show dramatic responses to corticosteroid. Unlike type 2, type 1 is characteristically associated with increasing levels of serum Ig G4 and positive serum autoantibodies, abundant infiltration of Ig G4-positive plasmacytes, frequent extrapancreatic lesions, and relapse. These findings have led several countries to propose diagnostic criteria for AIP, which consist of essentially similar diagnostic items; however, several differences exist for each country, mainly due to differences in the definition of AIP and the modalities used to diagnose this disease. An attempt to unite the diagnostic criteria worldwide was made with the publication in 2011 of the international consensus diagnostic criteria for AIP, established at the 2010 Congress of the International Association of Pancreatology(IAP). | Hiroyuki Matsubayashi Naomi Kakushima Kohei Takizawa Masaki Tanaka Kenichiro Imai Kinichi Hotta Hiroyuki Ono | 2014 | World Journal of Gastroenterology2014，20，44： | 17 |
| 13 | Current status of function-preserving surgery for gastric cancer显示文摘Recent advances in diagnostic techniques have allowed the diagnosis of gastric cancer(GC)at an early stage.Due to the low incidence of lymph node metastasis and favorable prognosis in early GC,function-preserving surgery which improves postoperative quality of life may be possible.Pylorus-preserving gastrectomy(PPG)is one such function-preserving procedure,which is expected to offer advantages with regards to dumping syndrome,bile reflux gastritis,and the frequency of flatus,although PPG may induce delayed gastric emptying.Proximal gastrectomy(PG)is another functionpreserving procedure,which is thought to be advantageous in terms of decreased duodenogastric reflux and good food reservoir function in the remnant stomach,although the incidence of heartburn or gastric fullness associated with this procedure is high.However,these disadvantages may be overcome by the reconstruction method used.The other important problem after PG is remnant GC,which was reported to occur in approximately 5%of patients.Therefore,the reconstruction technique used with PG should facilitate postoperativeendoscopic examinations for early detection and treatment of remnant gastric carcinoma.Oncologic safety seems to be assured in both procedures,if the preoperative diagnosis is accurate.Patient selection should be carefully considered.Although many retrospective studies have demonstrated the utility of function-preserving surgery,no consensus on whether to adopt functionpreserving surgery as the standard of care has been reached.Further prospective randomized controlled trials are necessary to evaluate survival and postoperative quality of life associated with function-preserving surgery. | Takuro Saito Yukinori Kurokawa Shuji Takiguchi Masaki Mori Yuichiro Doki | 2014 | World Journal of Gastroenterology2014，20，46： | 17 |
| 14 | Gastric adenocarcinoma of fundic gland type: Five cases treated with endoscopic resection显示文摘Recently,a new disease entity termed gastric adenocarcinoma of fundic gland type(GA-FG) was proposed.We treated five cases of GA-FG with endoscopic submucosal dissection.All tumors were small and located in the upper third of the stomach.Four tumors were macroscopically identified as 0-IIa and one was identified as 0-Ⅱb.Narrow-band imaging with magnifying endoscopy showed an irregular microvascular pattern in 2 cases and a regular microvascular pattern in the remainder.All tumors arose from the deep layer of the lamina propria mucosae and showed submucosal invasion.Lymphatic invasion was seen only in one case,while no venous invasion was recognized.All tumors were positive for pepsinogen-Ⅰ and MUC6 by immunohistochemistry.None showed p53 overexpression,and the labeling index of Ki-67 was low in all cases.All cases have been free from recurrence or metastasis.Herein,we discussed the clinicopathological features of GA-FG in comparison with past reports. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2015 | World Journal of Gastroenterology2015，21，26： | 16 |

| 16 | Efficacy of treatment with rebamipide for endoscopic submucosal dissection-induced ulcers显示文摘AIM:To prospectively compare the healing rates of endoscopic submucosal dissection(ESD)-induced ulcers treated with either a proton-pump inhibitor(PPI)or rebamipide.METHODS:We examined 90 patients with early gastric cancer who had undergone ESD.All patients were administered an intravenous infusion of the PPI lansoprazole(20 mg)every 12 h for 2 d,followed by oral administration of lansoprazole(30 mg/d,5 d).After7-d treatment,the patients were randomly assigned to 2 groups and received either lansoprazole(30 mg/d orally,n=45;PPI group)or rebamipide(300 mg orally,three times a day;n=45;rebamipide group).At 4and 8 wk after ESD,the ulcer outcomes in the 2 groups were compared.RESULTS:No significant differences were noted in patient age,underlying disease,tumor location,Helicobacter pylori infection rate,or ESD-induced ulcersize between the 2 groups.At both 4 and 8 wk,the healing rates of ESD-induced ulcers were similar in the PPI-treated and the rebamipide-treated patients(4 wk:PPI,27.2%;rebamipide,33.3%;P=0.5341;8 wk:PPI,90.9%;rebamipide,93.3%;P=0.6710).At 8 wk,the rates of granulation lesions following ulcer healing were significantly higher in the PPI-treated group(13.6%)than in the rebamipide-treated group(0.0%;P=0.0103).Ulcer-related symptoms were similar in the2 treatment groups at 8 wk.The medication cost of 8-wk treatment with the PPI was 10945 yen vs 4889 yen for rebamipide.No ulcer bleeding or complications due to the drugs were observed in either treatment group.CONCLUSION:The healing rate of ESD-induced ulcers was similar with rebamipide or PPI treatment;however,rebamipide treatment is more cost-effective and prevents granulation lesions following ulcer healing. | Masaki Takayama Shigenaga Matsui Masanori Kawasaki Yutaka Asakuma Toshiharu Sakurai Hiroshi Kashida Masatoshi Kudo | 2013 | World Journal of Gastroenterology2013，19，34： | 15 |

| 18 | Enhancing mechanical behaviors of collapsible soil using two biopolymers显示文摘This study aims to investigate the possibility of using biopolymer(environmental friendly material) to enhance the mechanical behaviors of collapsible soil.Two types of biopolymers were(xanthan gum and guar gum) used in this study due to their stable behaviors under severe conditions and their availability with reasonable prices.The experimental program focused on three major soil properties,i.e.compaction characterizations,collapsible potential and shear parameters.These three properties are essential in process of soil improvement.Different biopolymer concentrations were used in this study and the experimental program was performed at two curing periods(soon after mixing the soil with the biopolymer and after one week curing time).Shear parameters were measured for the treated specimens under both soaked and unsoaked conditions,while a collapsible potential test was performed under different mixing conditions(wet mix and dry mix).A numerical model was built to predict the behavior of the treated collapsible soil after and before water immersing.The results indicated that the ability of both xanthan gum and guar gum can be used as improvement materials for collapsible soil treatment.The collapsible potential has been reduced from 9%to 1%after mixing the soil with 2%biopolymer concentration in the wet case.After one week curing,the cohesion has been increased from 8.5 kPa to105 kPa by increasing the xanthan gum concentration from zero to 2%,leading to an overall improvement in soil shear strength.It also proves that the guar gum is superior to the xanthan gum.The shear strength of soil can be increased by about 30%when using the guar gum in comparison with the xanthan gum at the same conditions;however,the collapsible potential of soil material will be reduced by about 20%. | Mohamed Ayeldeen Abdelazim Negm Mostafa El-Sawwaf Masaki Kitazume | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，2： | 14 |
| 19 | A rare case of hyaline-type Castleman disease in the liver显示文摘Castleman disease often develops in the neck, mediastinum and pulmonary hilum. Its onset in the peritoneal cavity is very rare. The patient, a woman in her 70s, was referred to our department for a detailed examination of an abdominal mass. On abdominal ultrasonography, computed tomography scan, magnetic resonance imaging and positron emission tomography, a mass approximately 15 mm in diameter was noted in the hepatic S6. We attempted radical treatment and conducted a laparoscope-assisted right lobectomy. On the basis of histopathological findings, the patient was diagnosed as having hyaline type Castleman disease in the liver, a very rare condition. | Hisaaki Miyoshi Shima Mimura Takako Nomura Joji Tani Asahiro Morishita Hideki Kobara Hirohito Mori Hirohito Yoneyama Akihiro Deguchi Takashi Himoto Naoki Yamamoto Keiichi Okano Yasuyuki Suzuki Tsutomu Masaki | 2013 | World Journal of Hepatology2013，5，7： | 14 |
| 20 | 4种水生植物根际磷素耗竭效应的比较显示文摘利用短期盆栽试验和抖根法研究了喜旱莲子草(Alternanthera philoxeroides)、香蒲(Typha latifolia)、慈姑(Sagittariasagittifolia)和芦苇(Phragmites communis)4种水生植物的根际磷素耗竭效应,分析了植物根冠比、根系形态、磷素吸收有效性和磷素利用有效性等差异,探讨了植物根际磷素耗竭效应的吸收利用调控机制.结果表明,与非根际土壤(有效磷含量为167.53μg.g-1)相比,喜旱莲子草、香蒲、慈姑和芦苇根际土壤的有效磷含量分别减少至80.17、124.37、155.38和161.75μg.g-1,水溶性磷含量分别减少了81%、42%、18%和16%.喜旱莲子草根系较小,但磷素吸收有效性高(1.32 mg.m-1),其磷素利用有效性不高(0.34 g.mg-1);香蒲的磷素吸收有效性虽然比喜旱莲子草低许多(0.52 mg.m-1),但其有强大的根系,且磷素利用有效性高(0.64 g.mg-1)、根冠比大(0.35).喜旱莲子草和香蒲耗竭根际磷素的能力高于慈姑和芦苇. | 王震宇 温胜芳 邢宝山 高冬梅 李锋民 胡洪营 Sakoda Akiyoshi Sagehashi Masaki | 2008 | 环境科学2008，29，9： | 14 |
